Title: Moulding toothed flanges for adhesive tape spool cores - to secure flanges into the hollow core ends
IPC: B65H75/14
Filed: 1975-10-08
Abstract: Moulded flanges for supporting materials wound on to cardboard core spools, where the flanges are injection moulded using sliding inserts which produce inclined teeth at intervals around the boss of the flange. The teeth have a smooth rise leading to a sharp crest which tends to deform and engage the core like a barb. Used esp. for flaking spools for storing tape coated with adhesive which are sufficiently non-migratory not to enhance the grip of a smooth flange/core interface. Flanges have two or pref. four hollow teeth uniformly distributed around the perimeter of the boss.

The cam is mounted on one of the two shafts (2, 3) of the gear pump. Depending on the direction of rotation, the pump drive gear (7), which meshes with a gear (8) on the crankshaft or an intermediate shaft, is fitted to the gear pump shaft nearest to or furthest from the lever.
Patent FR-2289743-A1 (FR)
Title: Gas turbine fuel regulator - has heater element anemometer to measure fuel flow rate to combustion chamber
IPC: F02C9/28
Filed: 1975-11-03
Abstract: The fuel supply to the turbine combustion chamber is delivered by a variable output pressure pump rotated at a speed dependent upon that of the turbine. The pump delivers fuel to a hydraulic oscillator containing filter elements and a hot wire anemometer to give signals corresponding to the fluid vibrations. The output signals together with the output signals from a second anemometer arranged in the oscillator collection chamber are fed to a summing amplifier which gives an output corresponding to the fuel flow rate to the combustion chamber to a display unit and a comparator. The comparator also receives an input from a unit responding to revolution speed temperature compressor output and required output. The comparator output is then used to regulate a hydraulic servo unit to vary the fuel pump delivery rate.
Patent FR-2291633-A1 (FR)
Title: Earth fault detection circuit using low frequency bias voltage - includes logic equipment and filters for monitoring leakage currents
IPC: H02H3/17
Filed: 1975-11-07
Abstract: The equipment injects a voltage into the circuit to be supervised which is at a frequency well below that of the power supply. This bias voltage is produced by a signal generator which also controls the detection logic. The bias current flowing in the power circuit is monitored and the resulting signal filtered in order to send back to the detector a signal at the original input frequency. Discrepancy between relative voltage levels can then be used to initiate alarms or trips. By selective integration spurious low frequency signals due to transient disturbances can be eliminated. The equipment frequency is typically a quarter of the power frequency. The circuit can also be applied to d.c. systems, for example thyristor fed field windings.

Title: Centrifugal decanter incorporating auxiliary feed pipe - which charges flocculating agent directly into liq. phase in basket, maximising effect
IPC: B01D21/01
Filed: 1976-04-05
Abstract: A process for centrifugal decantation of suspensions, in which a flocculating agent is added to agglomerate the solid particles, incorporates introducing the flocculating agent int the decanter so that it comes into direct contact with the liq. phase rotating in the basket. Auxiliary pipe is near to the feed pipe and discharges into a chamber communicating with the annular space pipe can be inside the feed pipe and pass through its wall to open into the corresp. chamber. Flocculating agent comes into direct contact with the mass of liq. in the basket. The flocculation takes place uniformly and the aggregates can be deposited against the wall without being broken by turbulence or impact. In addition the flocculating agent acts in the liq. already partly free of heavy particles. The action is therefore more efficient, the quantity needed is less and the prod. is drier.
